Cavallaro, "Low Power VLSI Architecture for Adaptive MAI Suppression in CDMA Using Multi-stage Convergence Masking Vector," 2005.https://hdl.handle.net/1911/19941Conference PaperIn this paper, we propose a novel low power and low complexity multi-stage Parallel-Residue-Compensation (PRC) architecture for enhanced MAI suppression in the CDMA systems. The accuracy of the interference cancellation is improved with a set of weights computed from an adaptive Normalized Least-Mean-Square (NLMS) algorithm. The physical meaning of the complete versus weighted interference cancellation is applied to clip the weights above a certain threshold. Multistage Convergence-Masking-Vector (CMV) is then proposed to combine with the clock gating as a dynamic power management scheme in the VLSI receiver architecture. This reduces the dynamic power consumption in the VLSI architecture by up to 90% with a negligible performance loss.engSoC architecturelow poweradaptiveMAIConference paperSoC architecturelow poweradaptiveMAIhttp://dx.doi.org/10.1109/VETECF.2005.1558407
